Robert Wayne Welch, 25, faces two counts of felony injury to child charges.

Court records show on April 2nd, the 4-month old baby was taken to a Boise hospital after sustaining a skull fracture and suffering from malnutrition. Welch's girlfriend says the baby had been vomiting for days.

When weighed at the hospital the baby's weight was 8 pounds. Doctors say he should have weighed between 12 and 14 pounds and the baby was "not being provided with enough calories."

Doctors also tell investigators that the baby is a victim of "severe physical abuse".

Welch has a preliminary hearing scheduled for April 25th at 8:15 a.m. His bail is set at $100,000.
